PACKING-RING.

Application filed October 23, 1915. Serial No. 57,536. m

To all whom it may concern 1- Be it known that I, CLARENCE It. BRYANT, a. citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented new and useful 4 k Packing-Rings, of which the following is a specification.

This inventionrelates to packing rings and has for its Object to produce a packing ring for the pistons of engines embodying twin members of novel formation and relation to each other whereby there is' presented an outer circumferential surface or workin face which is entirely free from open joints through which pressure or fluid may escape and thereby enabling the ring to efficiently hold compression by insuring against leakage, the construction of the ring as a whole also preventing the scoring of the cylinder wall.

- A. further objectof the invention is to produce two members which are identical inform, size and weight, resulting in a perfectly balanced ring, are so formed as to prevent any relative rotati've movement thereof, thereby eliminating the necessity of using a dowel pin or like expedient While presenting an endless or continuous unbroken working face.

With the above and other objects in view, the invention consists in the novel construc tion, eombinationand arrangement of parts, as herein described, illustrated and claimed.

In the accompanying drawings:-

F i ure 1 is a plan view looking town-rd one ace of the complete ring.

Fig. 2 is a plan view looking toward the opposite face of the ring.

a Fig. 3*is a perspective view showing members, of the ring separated.

the

The ring contemplated in this invention I comprises twin members designated at and B. Each member comprises a body 1 which is split as shown at 2. Each memberis also provided along the meeting face thereof with an eecentrieor creseentshaped flange 3' prolecting sirfliciently to fully overlap the end portions of the other m mber, the end portions of both members being also tapered and eccentric as sholwn at ttoagree with the curvature of the inner surface of the flange 3 of the opposing members.

The twin members whenp eversely disposed eachpther.

assembled are the members of which- \Vhen the two members are associatedln their proper relation to,each,other, a comv plete ring of uniform thickness is produced and the outer surface of the complete ring is not interrupted or broken by any joints but presents a practically continuous or endless working face avoiding any leakage of compression between the packing ring and the cylinder wall and also preventing scoring of the cylinder-wall. Furthermore, by reason of the eccentricmeeting faces of the flanges 4 and the end portionsof the members, relative rotative movement of said members to each other is prevented with out the necessity of employing a dowel pin or similar expedient. The packing fr'mg; hereinabove described is especially adapted for use in connection with the pistons of engines or pumps of any kind requiring high compression and a fluid tight Contact between the piston and cylinder wall.

Having thus described my invention, I claim z-' 1. A. packing ring, comprising a plural ity of split members, one of the same being formed on its lateral meeting face with a projecting flange, and said members being disposed to one another so that said flange overlaps exteriorly the end portions of another member.

2. A packing ring, comprising two split members, one of the same being formed on its lateral meetin face with a projecting flange, the members being disposed reversely to each other with said flange overping exteriorly the end portions of the er member.

3. A packing ring, comprising a plurality of split members, each formed on its lateral meeting face with'aprojecting flange, said members being disposed to one another so that the flange off one member overlaps exteriorly the end portions of another member.

4. A packing ring, comprising two split members, each formed on its lateral meeting faoe'with' a projectingiflang'e, the mem bers being disposed reversely to each other swiththe flange of one member overlapping la ot specification of Letters Patent. p t i fdjuj 15, 9

exteriorly the end portions of the other member.

5. A peeking ring, comprising two split members, each formed on its leterelv meeting face with a projecting flange having an inner eccentric face, the members being disposed reversely to each other with the eccentric face of the flange of one member overlapping the end portions of the other member.

In testimony whereof I afiix my signature in presence of two witnesses.

It is hereby certified that the name of the assignee in Letters Patent N 0. 1,309,609,

granted July 15, 1919, npon the application of Clarence R.
